PIC16LF19176T-I/PT - 8-bit XLP MCU, 28KB Flash, 32MHz | Microchip
MPN: PIC16LF19176T-I/PT ✓ فعالPIC16LF19176T-I/PT نمای کلی
Microcontrollers are programmable embedded computing devices that integrate a CPU, memory, and peripherals onto a single silicon die. Within that hierarchy, an 8-bit MCU like the PIC16LF19176 belongs to the PIC16 family of microcontrollers, which is a sub-family of the larger PIC microcontroller line, itself a major branch of the embedded microcontroller (MCU) product category, ultimately classified under integrated circuits and semiconductors. Engineers pick 8-bit MCUs when cost, deterministic interrupt response, and low power outweigh the raw throughput of 32-bit cores.
This device targets battery-powered human-machine interfaces. XLP technology gives typical deep-sleep currents in the nanoamp range (per the datasheet IDD/DATA specifications), while the LCD charge pump supports glass types that require voltage rails above VDD. On-chip 12-bit ADC2 with oversampling and Burst Accumulate modes reduces external signal-conditioning cost; the DAC enables setpoint generation without a separate chip.
The CIPs - Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), Signal Measurement Timer (SMT), and Zero-Cross Detect (ZCD) - let timing- and waveform-sensitive functions run without CPU intervention, freeing the core for application code. Peripheral Pin Select (PPS) provides flexible digital I/O mapping across 35 I/O pins, easing PCB routing for mixed-signal boards.
Typical applications include battery-powered consumer products with segmented LCDs (thermometers, blood-pressure monitors, remote controls), industrial sensor transmitters, IoT edge nodes, white-goods user interfaces, and metering/utility devices that demand long battery life and integrated analog signal chains.
When designing with this part, verify the chosen package variant against board space early: the 44-pin TQFP in this MPN is the largest of the family, providing the most I/O; smaller 28-pin or 40-pin variants may require remapping signals. Also confirm the operating voltage window supports your LCD bias requirements, since some glass choices drive VDD toward the upper 3.6 V limit.

کاربردهای معمول
PIC16LF19176T-I/PT مناسب است برای 6 کاربردs: Battery-Powered Thermometer with LCD, Industrial Sensor Transmitter, Blood Pressure Monitor, Home Appliance User Interface, Battery-Powered IoT Edge Node, Smart Meter / Utility Endpoint.
Battery-Powered Thermometer with LCD
The PIC16LF19176T-I/PT is well-suited for battery-powered digital thermometers requiring a segmented LCD readout. Its 1.8 V to 3.6 V operating range supports 2x AA or coin-cell power, while XLP technology delivers nanoamp-range sleep currents for multi-year battery life. The integrated LCD charge pump drives common glass types directly from low VDD, eliminating the external booster IC. The 12-bit ADC2 reads the thermistor or RTD with averaging burst modes, and the RTCC handles timed wake-ups to refresh the LCD only when needed.
پیشنهادی
Industrial Sensor Transmitter
In 4-20 mA or wireless sensor transmitters, the PIC16LF19176T-I/PT combines the 12-bit ADC2 for precision sensor readout with the CWG/SMT peripherals that implement timers and waveform generation in hardware without CPU load. The 32 MHz core gives plenty of headroom for protocol stacks like HART or IO-Link, while the 256-byte EEPROM stores calibration coefficients across temperature cycles. PPS routing simplifies PCB layout when analog and digital signals share the same pins.
پیشنهادی
Blood Pressure Monitor
The PIC16LF19176T-I/PT powers blood pressure cuffs where a segmented LCD displays systolic/diastolic readings and the 12-bit ADC2 samples the pressure transducer signal. The integrated DAC generates the slow pressure ramp during inflation, while CWG manages motor control for the pump - all without loading the CPU. XLP modes preserve battery life between measurements, and the device's 35 I/O pins provide room for buttons, buzzer drivers, and IrDA-style data export.
پیشنهادی
Home Appliance User Interface
The PIC16LF19176T-I/PT is a strong fit for washing machines, microwave ovens, and dishwashers where a segmented LCD is paired with capacitive or mechanical buttons. The 35 I/O pins handle multiple keypad rows, rotary encoder inputs, relay drivers, and buzzer control. PPS lets the designer remap UART/I2C to unused pins for PCB routing flexibility, and the CLC/CWG peripherals offload waveform generation for triac-controlled heater elements.
پیشنهادی
Battery-Powered IoT Edge Node
The PIC16LF19176T-I/PT serves as an edge node MCU in IoT sensors transmitting over BLE, LoRa, or sub-GHz radios. XLP sleep currents measured in nanoamps let the node sit dormant for months, waking on RTCC alarm or external interrupt to take a sensor reading and transmit. The 32 KB Flash fits full LoRaWAN or BLE-stack-lite code, and the 12-bit ADC with averaging oversamples the sensor for noise-immune results.
پیشنهادی
Smart Meter / Utility Endpoint
Utility metering endpoints benefit from the PIC16LF19176T-I/PT's integrated LCD with charge pump for displays of kWh or gas usage, combined with the 12-bit ADC2 for current sensing and the CWG for pulse generation. The 256-byte EEPROM stores tariff schedules and tamper flags non-volatilely. XLP current is low enough that meter batteries last the full certification lifetime, while the 32 MIPS core handles metering math, encryption helpers, and communication scheduling.

یادداشت‌های طراحی
Estimated: at VDD=3.3 V and 32 MHz active CPU, the PIC16LF19176T-I/PT typically draws about 2-4 mA active current per the datasheet IDD tables. In XLP sleep modes (Sleep, Retention, Deep Sleep), the device drops into nanoamp range, which is critical for battery-powered LCD meters that need to sit idle for years. Use the RTCC or external interrupt to wake the MCU only when a button-press occurs or a periodic measurement is due. Decouple VDD with a 100 nF X7R ceramic placed within 5 mm of the VDD pin, plus a bulk 1-10 uF capacitor on AVDD to keep analog readings clean.
Route the LCD segment lines with minimal crossovers and keep them away from high-speed switching signals like oscillators and PWM outputs to reduce ghost-segment flicker. The 44-pin TQFP has ample ground and VDD pins (pin 13/37 for VSS, pin 14/38 for VDD) - connect each pair directly to its respective plane. Avoid running long analog traces near digital-only LCD segments. The COM0-COM3 pins should return to a clean ground and have their own bypass capacitance of 100 nF to handle charge-pump switching noise.
When migrating from PIC16F19176 to PIC16LF19176, confirm that the chosen VDD stays above 1.8 V in all operating conditions - some LDO regulators and battery chemistries can dip below 1.8 V near end-of-life, causing brown-out resets. Always set the BOR (brown-out reset) voltage threshold slightly above the minimum supply. Watch out for ICD/ICSP pin conflicts: RB6/RB7 are shared with programming, so design the PCB so probe clips can still reach them on assembled boards for in-circuit debug.
